Then...contrast that to an amazing experience I had at the OTHER conference a few weeks ago, listening to an amazing organist improvise throughout a Tridentine Mass...the music never ended. (barely.) and it lifted your soul to heaven. There was no "theme," or hymn that it was based off of. (That I could immediately tell, at least.) Here's the TEN minute organ communion that absolutely made my week: http://music.dierschow.com/2010Colloquium/26Mass/Organ%20Interlude%20Communion.mp3
What a contrast. I guess that is improvising in the "french style." that of Langlais, even Messiaen. And that is...Catholic. That is what we use at Mass. The most holy Sacrifice of the Mass, where the music actually occurs *during* liturgical action.
I need to think more about this, but there is just something... different about that. And that is my goal in improvising. To be able to play like that. I suppose I need to study Langlais to do that. We will see if K will let me play Suite Medievale for my recital? :-)
